   <ul>
    <li>Full backup: <span id="TIDB_00072__en-us_topic_0000001862053249_ph48664393114">backs up all data at a specific point in time, regardless of whether the data has been modified since the last backup. In the case of large data volumes, this backup type may take a long time and occupy a large amount of storage space.</span></li>
    <li>Log backup backs up archived database operation logs. To manually back up logs, ensure that a full backup copy exists.</li>
    <li>Copy verification: verifies the integrity of a copy after the backup is complete or before the copy is used for restoration.</li>
    <li>Source deduplication: deduplicates backup data at the source end before the data is sent to the target end. This technology saves network transmission bandwidth and storage space.</li>
    <li>Transmission and storage encryption: adopts the AES256 encryption algorithm to encrypt backup data.</li>
